Abstract
A function generator is described that can be configured as a combinational logic, sequential logic, or routing cell. The function generator couples to a plurality of selector blocks that select a wire from a plurality of inputs. The selected wires are inputs to a function generator. The function generator, when configured as a combinational logic cell, can generate any function of its inputs. The function generator, when configured as a sequential logic cell, behaves as a register, where any of the inputs can be directed to input data, clear, clock enable, or reset signals. The register is configurable to a falling or rising edge flip-flop or a positive or negative level sensitive latch. As a routing element, logic cells selects one of its inputs. The output of the programmable cell can fan out to one or more inputs of another integrated cell.
